WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 405,635, dated June 18,1889.

Application filed August 18, 1888- Serial No. 283,090- (No model.)

To all whom it may concern:

Be it known that I, ROWLAND WESTON, of East Saginaw, in the county ofSaginaw and State of Michigan, have invented new and useful Improvementsin ater-Closets, of which the following is a description.

My invention relates to an improvement in Water-closets, and has for itsobject to provide a closet of simple and effective construction, whichmay be left unattended for any length of time and remain filled withwater; and a further objectof the invention is to provide a simple meansfor automatically discharging Water from the flushing-tank into the bowlshould the latter become empty through evaporation or otherwise.

The invention consists in the construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference 'is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the views.

Figure 1 is a central vertical section through the flushing-tank,illustrating the valve as closed. Fig. 2 is a central vertical sectionthrough the bowl. Fig. 3 is a central vertical section through theflushing-tank, illustrating the valve as open to admit water to thebowl; and Fig. 4 is a front elevation of the bowl, partly broken away.

In carrying out the invention the bowl is made double at the upper edgeto provide an annular chamber 11, in the lower wall of which chamber aseries of perforations 12 is produced. A vertical extension 13 is builtupon the rear of the bowl, which extension joins the upper edge of thesame, whereby a chamber 14 is formed intersecting the upper annularchamber 11. The chamber 14,I denominate, for convenience, theflushingchamber. The wall of the bowl proper constitutes the inner wallof the chamber 14, and

in the said wall near the bottom one or more apertures 15 are made toadmit water to the said bowl.

The bowl 10, with the exception above noted, may be of any desiredconstruction, being provided with a trap-valve 16, operated by aweighted lever 17, or otherwise, as desired.

v In the rear wall of the flushing-chamber, at or near its bottom, aneck is formed, and to said neck a flushing-pipe 18 is coupled,whichpipe is carried upward to a connection with the flushing-tank 19. Theflushing-tank is provided with a water-supply pipe 20, preferablyentering it at the end opposite to that receiving the flushing-pipe, andthe"eXit of the water from the supply-pipe is controlled by the usualfloat-valve 21, as shown in Fig. 1.

A valve-seat 22 is introduced in the bottom of the tank, consisting of athimble 23, having a flanged or cup-shaped head 24, and the saidvalve-seat is so located that the body of the thimble will enter theflushing-pipe, or the said pipe be coupled thereto, and the head restupon the bottom of the tank, as best shown in Fig. 1.

The valve 25, consisting of a disk 26, of greater diameter than the headof the thimble,'constitutes the seat, which disk is secured in anyapproved manner to the under surface of a preferably cylindrical float27. The valve 25 is completed by attaching a smaller disk 28 to theaforesaid disk 26,

adapted to close the opening of the thimblebody, and the addition to thesmaller disk of a section of pipe 29, having a series of vertical slotscut from the bottom upward.

The slotted pipe-section 29 is purposed to slide in the body of thethimble. A second float 30 is held a distance above the float 27 by atubular post 31, attached to and extending through the lower float to aconnection with the pipe-section 29. The two floats and the valve areadapted to have a vertical movement, and are guided in said movement bya pin 32, integral with the upper float, passing upward between twospaced guiderods 33, secured to the upper edge of the tank.

The bowl when not in use is about half filled with water, which coversthe opening 15, and as long as the said opening remains covered thecolumn of water in the flushingpipe remains intact. WVhen, however, thetrap-valve 16 is opened, the water in the bowl, running out, uncoversthe opening 15, and the water in the flushingpipe floods the chambers14: and 11, and passes from thence to the bowl, and as the water in. theflushingpipe escapes the suction of the same is removed from the valve,and as the valve is held closed by said suction the balance of thefloats 27 and 30 is broken, and said floats rise and unseat the valve,the upper float touching the top of the tank. The floats remain elevateduntil sufficient water passes out to fill the flushing-pipe, whereuponthe valve again closes, the water in the bowl having in the meanwhilerisen above the aperture 15.

The upper float 30 will prevent overflow from the tank should theball-valve 21 refuse to act, as the said float 30 will raise the valve25 and the water will pass down into the bowl, which may be providedwith an overflow.

A small pipe 34 may, if desired, belocated in the tank, one end whereofextends above the tank, and the other end is located beneath the valve25. The purpose of the said pipe is to admit air to the tank and valveto held closed by the suction exerted by the column of water in thestand-pipe, released when the bowl is emptied to again fill thestand-pipe, and be closed by its weight when the water inthe tank isinsufficient to float it, substantially as set forth.

2. The combination, with the water-closet bowl having a trap-valvenormally closing its outlet to hold" the water in the bowl and anaperture belowthe water-line, of a normallyfilledstand-pipecommunicating with the bowl through said aperture, a tank with thebottom of which the upper end of the stand-pipe communicates, afloat-valve normally closing the said upper end of the pipe against theentrance of either air or water and held in its closed position againstits tendency to rise by 1 the rear of the same, forming aflushing-chamber provided with an outlet at the bottom leading into thebowl, a tank, and a pipe connecting the tank and flushing-chamber, oftwo connected spaced floats in said tank, a 5 guide attached to theupper float,and a valve secured to the under side of the lower floatadapted to close the fiushing-tube, substantially as shown anddescribed.

4. In a water-closet, the combination, with a bowl, a vertical extensionproduced upon the rear of the same, forming a flushing-chamdifferentdiameters, and a central slottedtube' adapted to enter theflushing-pipe, substantially as shown and described.
